BAND-FASTENING.

SPECIFICATION forming part of Letters Patent No. 391,340, dated October 16, 1888.

Serial No. 283,516. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN M. SCOTT, a citizen ofthe United States of America,residing at Ra cine, in the county of Racine and State of VViscousin, have invented certain new and useful Improvements in Band-Fastenings; and I do hereby declare the following to' be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referenee being bad to the accompanying drawings, and to letters or figures of reference marked thereon,which form a part of this specification.

This invention relates to means for connecting or clamping together the ends of hoops or bands employed in surrounding and holding or confining the staves of tanks, cisterns, and the like; and it consists in the novel features hereinafter fully set forth.

In the accompanying drawings, illustrating my invention, Figure 1 shows a section of a barrel, tank, or well-cistern with my improvement applied thereto, also shown in section. Fig. 2 illustrates an enlarged longitudinal section of one of the clamping-heads with the clamping rod in position therein, and also showing a part of a hoop or band in a clamped position. Fig. 3 is a bottom plan view of a part of the clamping-head. Fig. 4 is a detail perspective view of a part of the head.

As both of the clamping heads are constructed precisely alike, a description of one only is necessary.

A indicates a metallic casting forming the main body of the clamp. This casting is made hollow, and has an enlarged end, a,witl1 a large openingp,therethrough merginginto a recess, a", which recess is continued in a recess, a", gradually tapering downward toward the opposite end a" of said casting. The end a has an increased thickness or re-enforcenient of metal, and is formed with an opening, aiwhich merges into a circular recess, a, in the top inner wall of the casting A. The top outer surface of the said casting is of an irregular-curved configuration, and the bottom, which bears against the staves of the tank, barrel, or cistern, is straight or substantially straight. The two ends of the casting are recessed or formed with an upward depression, a for the passage thereunder of the band or hoop B. Across the under side of the casting and nearer the end a thereof a bar or rod, A, extends, over which the hoop or band B is passed. This bar or rod A may be formed integral with or se cured to the casting, the metal of said casting at this point being slightly increased in thickness to re-enforce the same and counterbalance the strain.

Vithin the opening a, in the end a of the casting A a removable grip, O, is loosely inserted. This grip O is formed by casting, and has an enlarged head, 0, as shown, substantially circular in contour, with a smooth-bored aperture, 0, extending therethrough. The said grip is irregular in form, the head 0 thereof being considerably larger than the remaining part thereof. In consequence of this enlargement of the head 0 the aperture 0, passing there'through to the rear of the grip, opens out through the top part thereofand forms a curved open recess,which separatesthe upper part of the grip into two parts. This rear recess and the aperture 0, of which the former is an ex tension, is brought into alignment with the recess a in the casting A when the parts are in clamping position, as shown in Figs. 1 and 2. The inner end of the said grip is curved in concave form, as at 0 and has a depending projection, c. This end as thus constructed bears against the band or hoop over the bar A and gradually presses it down in curved form over said bar, and thereby provides a clamping-bend, and atthe same time avoids the formation of too short a bend,which would have a tendency to break the band or hoop.

A clamping rod or bolt, D, extends from one head, A, to the other and passes out through the aperture a in one head, in through said aperture in the other head, through and bearing in the recess a above the bar A, and through the aperture 0 in the grip 0. Both ends of said rod D are screwthreaded, as at d, and are adapted to receive nuts D, which,when the band or hoop is tightened up, bear against the grip O, which in turn is forced against the band or hoop B on one side of the bar or rod A. The nuts D can be tightened from both ends of the rod D simultaneously, or only one be tightened at a time, the clamping operation being the same in either case.

To place the band or hoop B in connection with the heads, the nuts D are loosened, the

rod or bolt D removed, together with the grip O, and the said bands inserted up overt-he bars A. The parts are then rearranged, as shown in Figs. 1 and 2, and the band tightened.

It will be observed that the heads A are constructed in such a manner as to accommodate the slope of the staves and bring the bolt or rod D in proper alignment with the heads, thereby avoiding the clamping of said rod by the contiguonsly-arranged ends a of the heads.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The herein-described clamp for uniting the ends of hoops or bands or tightening the same, consisting of a pair of heads recessed and apertured, as set forth, and provided with cross-bars, grips loosely mounted therein, and arod extending through one head into and through the opposite head, having screw- In testimony whereof I affix my signature in presence oftwo witnesses.
